Abstract
A direct thermal printer device that can be used in any application using thermal printers. A direct thermal printer creates images on thermally active medium by applying light energy or radiant thermal energy created by a thermal heat source to create the heat necessary for generating an image on the thermal medium. The thermal energy source may be a laser, a high output light source, or a radiant heating element.
Claims1
A direct thermal printer, comprising:
- a direct thermal print head comprising an array of thermal energy sources directly radiantly coupled to a thermal print medium;
- a thermal print medium drive mechanism holding the thermal print medium in noncontacting proximity to the direct thermal print head without a thermal energy modulator interposed between the thermal print medium and the direct thermal print head;
- and
- a controller coupled to the direct thermal print head and the thermal print medium drive mechanism, wherein the output power of the thermal energy sources are individually controllable by the controller,
- wherein the thermal energy sources are heater elements.
